Pulling power weakens sharply with every subsequent millimeter of gap. Remember that every additional insulation layer (e.g., contamination, paint, rust) noticeably weakens the grip. Magnets operate most effectively during direct contact; distance kills the power. See how flashily the pull force drop, when the product does not adhere tightly to the steel surface. When designing the assembly, discard redundant distances.

The table below defines the theoretical force required to initiate the slippage of the magnet vertically on a upright steel plate (assuming typical friction coefficient). This value is a function of the gap size between the magnet and the metal.

When hanging a holder on a vertical wall (e.g., a board), it will maintain only about 1/5 of nominal attraction strength. Gravitational force and a low friction coefficient influence the fact that products slide down faster than they pop off the substrate. Planning a vertical fastening? Remember that the shear force is much weaker than the maximum static pull force. On a smooth steel, the element will slide down under a noticeably lighter cargo. Using a rubber coating can significantly raise the stability.

A thin metal plate is unable to conduct the entire magnetic field, which weakens actual performance of the magnet. Should you install a neodymium to a thin surface, the magnetism will pass right through and the holding will be smaller. To utilize 100% of this magnet's power, you need a suitably thick backing of steel. The material oversaturation causes that on delicate walls (e.g., thin profiles), the holder holds weaker. We advise picking the steel dimension based on the following data.

Ordinary NdFeB products irreversibly lose strength past the thermal threshold. Avoid high temperatures – high temperature can irreversibly destroy this magnet. With increasing heat, the magnet's capacity briefly decreases. Refrain from using this product close to heaters higher than its operating temperature limit. Too high temperature will cause irreversible degradation of magnetic properties.

*Engineering note: Thermal stability depends not only on the material grade, but also on the magnet's shape. Thin magnets (low permeance coefficient) risk losing magnetic properties under lower heat stress compared to rod magnets. Red status in the table signals permanent field degradation for this specific geometry.

Two magnetic products interact from a wider radius than a neodymium and metal combination. Such a system of two magnets creates a more powerful interaction and a wider radius of operation. Planning to create a solid fastener? Utilize two neodymiums instead of a neodymium and a steel. Be careful that when connecting a pair of magnets, the collision energy is huge. The repulsion force is a bit weaker than the attraction, but still significant.
*The magnetic induction between like poles reaches ~0 Gs at the midpoint between the magnets (resulting from vector opposition).
Important: Figures refer to friction force of dual same magnets (friction ~0.15 for Ni-Ni layer).

A strong magnetic field is a real danger to electronic devices as well as pacemakers. These neodymiums produce a field that prevents correct functioning of sensitive medical devices. Be aware: the unseen radiation acts through matter and housings. Special caution must be taken by people with cochlear implants and insulin pumps. Influence will be felt by: automatic timepieces, remotes, membranes, and screens. Do not place the magnet near cards, hard drives, or sensitive navigation tools.

Magnetic elements are delicate – a collision with steel causes immediate chipping. Pay attention to connection velocity – a neodymium left loose turns into a projectile. Kinetic force can destroy the magnet or dangerous crushing to skin. Be sure to control the product during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h ends with a crack of the magnet. Use safety goggles when working with powerful specimens.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.32

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

This product is a very powerful plate magnet made of NdFeB material, which, with dimensions of 20x3x2 mm and a weight of 0.9 g, guarantees the highest quality connection. This magnetic block with a force of 22.90 N is ready for shipment in 24h, allowing for rapid realization of your project. Furthermore, its Ni-Cu-Ni coating secures it against corrosion in standard operating conditions, giving it an aesthetic appearance.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. To separate the MPL 20x3x2 / N38 model, firmly slide one magnet over the edge of the other until the attraction force decreases. We recommend extreme caution, because after separation, the magnets may want to violently snap back together, which threatens pinching the skin. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

They constitute a key element in the production of generators and material handling systems. Thanks to the flat surface and high force (approx. 2.33 kg), they are ideal as closers in furniture making and mounting elements in automation. Customers often choose this model for hanging tools on strips and for advanced DIY and modeling projects, where precision and power count.

For mounting flat magnets MPL 20x3x2 / N38, we recommend utilizing two-component adhesives (e.g., UHU Endfest, Distal), which ensure a durable bond with metal or plastic. For lighter applications or mounting on smooth surfaces, branded foam tape (e.g., 3M VHB) will work, provided the surface is perfectly degreased. Remember to roughen and wash the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 20x3x2 / N38 model is magnetized axially (dimension 2 mm), which means that the N and S poles are located on its largest, flat surfaces. Thanks to this, it works best when "sticking" to sheet metal or another magnet with a large surface area. Such a pole arrangement ensures maximum holding capacity when pressing against the sheet, creating a closed magnetic circuit.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 3 mm (width), and 2 mm (thickness). It is a magnetic block with dimensions 20x3x2 mm and a self-weight of 0.9 g, ready to work at temperatures up to 80°C. The product meets the standards for N38 grade magnets.

Pros as well as cons of Nd₂Fe₁₄B magnets.

Pros

Apart from their strong magnetic energy, neodymium magnets have these key benefits:

Their power is maintained, and after approximately ten years it drops only by ~1% (according to research),
Neodymium magnets are characterized by exceptionally resistant to magnetic field loss caused by external magnetic fields,
The use of an shiny coating of noble metals (nickel, gold, silver) causes the element to look better,
Neodymium magnets ensure maximum magnetic induction on a small area, which allows for strong attraction,
Thanks to resistance to high temperature, they are able to function (depending on the shape) even at temperatures up to 230°C and higher...
Thanks to modularity in shaping and the capacity to adapt to client solutions,
Key role in modern industrial fields – they are utilized in mass storage devices, electric motors, medical equipment, also other advanced devices.
Compactness – despite small sizes they generate large force, making them ideal for precision applications

Disadvantages

Disadvantages of neodymium magnets:

Susceptibility to cracking is one of their disadvantages. Upon strong impact they can break. We recommend keeping them in a special holder, which not only secures them against impacts but also increases their durability
We warn that neodymium magnets can lose their strength at high temperatures. To prevent this, we advise our specialized [AH] magnets, which work effectively even at 230°C.
When exposed to humidity, magnets usually rust. For applications outside, it is recommended to use protective magnets, such as magnets in rubber or plastics, which secure oxidation as well as corrosion.
Due to limitations in producing nuts and complicated forms in magnets, we recommend using cover - magnetic holder.
Potential hazard to health – tiny shards of magnets pose a threat, in case of ingestion, which gains importance in the aspect of protecting the youngest. Additionally, tiny parts of these products are able to be problematic in diagnostics medical after entering the body.
High unit price – neodymium magnets cost more than other types of magnets (e.g. ferrite), which increases costs of application in large quantities

Holding force characteristics

Best holding force of the magnet in ideal parameters – what contributes to it?

Magnet power was determined for optimal configuration, assuming:

using a base made of mild steel, acting as a circuit closing element
whose transverse dimension reaches at least 10 mm
with a surface perfectly flat
with direct contact (no coatings)
under perpendicular application of breakaway force (90-degree angle)
at room temperature

Impact of factors on magnetic holding capacity in practice

Holding efficiency impacted by specific conditions, such as (from most important):

Air gap (between the magnet and the plate), as even a tiny distance (e.g. 0.5 mm) results in a drastic drop in force by up to 50% (this also applies to varnish, rust or dirt).
Pull-off angle – note that the magnet has greatest strength perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Plate thickness – too thin plate causes magnetic saturation, causing part of the flux to be lost into the air.
Metal type – different alloys attracts identically. High carbon content worsen the attraction effect.
Smoothness – ideal contact is possible only on smooth steel. Any scratches and bumps create air cushions, weakening the magnet.
Operating temperature – NdFeB sinters have a sensitivity to temperature. At higher temperatures they are weaker, and at low temperatures they can be stronger (up to a certain limit).

Lifting capacity was measured with the use of a polished steel plate of optimal thickness (min. 20 mm), under vertically applied force, in contrast under attempts to slide the magnet the holding force is lower. In addition, even a slight gap between the magnet’s surface and the plate lowers the lifting capacity.

Warnings

This is not a toy

Only for adults. Small elements pose a choking risk, causing intestinal necrosis. Store out of reach of kids and pets.

Handling rules

Handle with care. Rare earth magnets attract from a distance and connect with huge force, often faster than you can move away.

Crushing force

Pinching hazard: The attraction force is so immense that it can result in blood blisters, crushing, and even bone fractures. Protective gloves are recommended.

Demagnetization risk

Keep cool. Neodymium magnets are sensitive to heat. If you require operation above 80°C, look for HT versions (H, SH, UH).

Risk of cracking

Despite the nickel coating, the material is brittle and cannot withstand shocks. Do not hit, as the magnet may shatter into sharp, dangerous pieces.

Metal Allergy

Nickel alert: The nickel-copper-nickel coating consists of nickel. If skin irritation occurs, cease working with magnets and wear gloves.

Data carriers

Do not bring magnets close to a wallet, laptop, or TV. The magnetism can irreversibly ruin these devices and erase data from cards.

GPS Danger

Remember: neodymium magnets generate a field that confuses precision electronics. Maintain a separation from your mobile, tablet, and navigation systems.

Danger to pacemakers

Patients with a pacemaker must keep an safe separation from magnets. The magnetic field can disrupt the operation of the life-saving device.

Dust is flammable

Powder produced during grinding of magnets is combustible. Do not drill into magnets unless you are an expert.
